While we recommend using the newest version of the image editor for all the most up to date features, it is possible to switch between editor versions. Note that when you switch between editors in settings that it will not impact previously uploaded content. All new uploads will open in the editor that you have active in settings. Click here to read why we recommend switching to the new editor.
Navigate to the Settings from the upper right menu. From the settings, choose Interface Settings. Check or uncheck the first box to control which editor you use. Regardless of the current editor, an image will always display in the editor it was originally uploaded into.
